Topic 5 Lesson 1 - Sixth Grade

Elevate Science Book

Hot molten material inside Earth, called magma, flows up through cracks in Earth's crust. This material cools to form solid rock. Over time, the rock can be eroded into small pieces. If enough small pieces collect, they may get packed together to form new rock.

Rock Cycle

​In the water cycle, water evaporates from the ocean and other bodies of water. Then it rises into the atmosphere and eventually falls back to Earth as precipitation. Rain and meltwater then flows to rivers, lakes, and the ocean.

Water Cycle

Water and Rock Cycles

Multiple Choice

Evaporation of water requires heat energy.

• I do not know.

• True

• False

• Maybe. I am not sure.

Multiple Choice

A group of parts that work together as a whole.

• Earth

• Rock cycle

• System

• Feedback

Earth's Spheres

The Earth system is made up of four main spheres or subsystems. Can you name them?

It is the relatively thin envelope of gases that forms Earth's outermost layer.

​It is made of air, a mixture of gases including nitrogen, oxygen, water vapor, carbon dioxide, and dust particles.

​Atmosphere

It contains Earth's weather, and it is the foundation for the different climates around the world.

​

Atmosphere

​It contains most of Earth's mass in the form of rock and metal. It includes the solid metal inner core, the liquid metal outer core, and the rocky mantle and crust.

​

Geosphere

It contains all of Earth's water, including water that cycles through the atmosphere. It also contains the CRYOSPHERE.

​Hydrosphere

It is the frozen component of the hydrosphere. It is made up of all the ice and snow on land, plus sea and lake ice.

​

​Cryosphere

It is the part of Earth that contains all living organisms.

​

​Biosphere

Multiple Choice

Earth's outermost layer that receives energy in the form of sunlight:

• Geosphere

• Biosphere

• Atmosphere

• Hydrosphere

Multiple Choice

In this sphere, liquid water absorbs energy from sunlight, and moderates the climate:

• Geosphere

• Biosphere

• Atmosphere

• Hydrosphere

Multiple Choice

In some locations, energy and new material make up the rocky outer layer of this sphere:

• Geosphere

• Biosphere

• Atmosphere

• Hydrosphere

Multiple Choice

Life has been found in every part of Earth, from the ice shelf of Antarctica to the Himalayan Mountains.

• Geosphere

• Biosphere

• Atmosphere

• Hydrosphere

It causes a process to slow down, or go in reverse.

​Negative Feedback

Feedback that reinforces, speeds up, or enhances the process that is already underway.

​Positive Feedback

Feedback

It returns, or gives back, information about itself, and that information results in a change.

Multiple Choice

An event in one sphere can affect another, which in turn can affect another.

• Yes.

• I do not know.

• Maybe; I am not sure.

• No.

Multiple Choice

This prefix means "land."

• Atmos-

• Geo-

• Bio-

• Hydro-

Draw

Draw an interaction between the atmosphere and the biosphere.
